SPECIFICATION forming part of Letters Patent No. 588,156, dated May 25, 1897.

Original application filed February 18, 1890, Serial No. 340,920. Divided and this application filed S t b r 2, 1892. Serial No. 444,925. (No model.)

To all whom it may concern:

Be it known that CHRISTOPHER LATHAM SHOLES, now deceased, but during his lifetime a citizen of the United States, and a 5 resident of Milwaukee, in the county of Milwaukee, State of Wisconsin, did invent certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

[O This invention relates to type-writing machines, and more particularly to the inkingribbon carrier, as hereinafter pointed out.

In a patent dated April 14, 1896, and numbered 558,428, Christopher Latham Sholes has i 5 broadly claimed an inking-ribbon and means for moving the same in two directions, one crosswise to the other, to utilize substantially the entire surface of the ribbon. In the particular embodiment of his invention therein illustrated the movement of the ribbon in one direction takes'place with or is eifected by the paper-carriage, and specific claims are also made in said patent directed to or based upon that particular form or embodiment. 2.5 The present embodiment of his invention contemplates a ribbon supporting and shifting mechanism distinct from the paper-carriage or mounted in the frame of the machine and not bodily movable with the carriage, but capable of automatically moving the ribbon transversely to the line of printing during the travel of the carriage, and also capable of automatically moving it longitudinally. So far as advised this is the earliest in- 5 stance of an automatic ribbon-moving mechanism of the character set forth, and hence it is intended herein to claim it broadly.

In the accompanying drawings, Figure 1 is a perspective View of a type-writing machine 40 embodying the invention; Fig. 2, a vertical sectional view illustrating portions of the mechanism; Fig. 3, a side or end elevation of the machine, and Fig. 4 a bottom plan view. The present invention is confined to the matters above indicated, and for this reason only so much of a type-writing machine will be described as is necessary toa full and clear comprehension of the ribbon supporting, feeding-and shifting devices.

The frame of the machine may be of any suitable construction, but is here represented as consisting of a top plate or table A, sustained by four legs or uprights B, a bar 0, extending across the front and ends of the machine, as shown in Figs. 1 and 4, and a platform D below the top or table A.

V and YV indicate rails or ways to support and guide a frame or carriage X, in which is carried a roll or platen N, and which carriage is here represented as provided with a bar Y at its rear side. The construction of the carriage is, however, immaterial to the present matter.

Type-bars G are arranged to strike at a common point and to print upon the paper carried by the roll or platen N as usual.

0 indicates a bar or sweep, one end of which is pivotally attached to the bar 0 of the frame and the other end of which extends upward at the rear side of the machine and is connected by a link D withthe bar Y or other part of the carriage. This bar 0 is formed with two lateral branches 7 and .9 near its pivot end, the former provided with a notch in which is seated one end of a link t, by which the arm 1* and the free end of spring B are connected.

From the end of arm 3 a bar or link to extends to and is pivotally connected with a flat bar E, the two ends of which project through slots or openings in the side portions of bar O of the main frame, as shown in Figs.

1, 2, and 4.

As will be readily understood upon reference to Fig. 4, the spring B tends to swing the bar or sweep 0 about its pivot or center of motion, and as this action takes place during travel of the carriage from right to left the outer end of arm 3 will swingtoward the front of the machine, and as the bar 0 is returned to its starting-point by the recession of the carriage the arm 5 will move backward or away from the front of the machine. In thus moving back and forth the arm .9 will, through link a, impart a forward- 5 and-backward movement to the bar E, the two ends of which are caused by a guide-rod F, Fig. 4, to move alike.

Rising from each end of the bar E is an upright or standard I, (well shown in Figs. 1, 2, and 3,) each of which carries a horizontal stem or spindle H below the table A to receive a ribbon-spool I, and each of which has above said table a lateral arm J, which serves as a ribbon support and guide to raise the inking-ribbon R above the type-bars and to hold it in proper relation to the platen-roll.

A nut r, screwed upon the end of each stem or spindle II, prevents the spool from workin oif.

The ribbon spools and guides being carried by and moving with the bar E, it follows that as the bar is moved back and forth the ribbon will be moved transversely to its length across the printing-point, and that as a consequence the entire width of the ribbon will be utilized instead of merely a narrow line thereof, as is usually the case.

To cause the longitudinal travel of the rib hen, the spools I are both made with a ratchet wheel or disk in at one end, with which engages a dog or pawl 00-, carried by a swinging arm or lever y, pivoted one to each upright or standard G, as shown in Fig. 2. A spring .2 serves to normally draw and hold back each of the arms or levers 1 or to return each after a forward movement. A throw-out lever K is pivoted to each standard or upright G and engages beneath a projection on the dog or pawl 00, serving to lift and hold the same out of engagement with its ratchet wheel or disk when desired, only one pawl and disk being in engagement at any one time.

The upper ends of the levers y bear against oblique guides or ways a, whereby as the bar E, during the recession of the carriage, moves toward the rear of the machine the levers y are thrown inward, feeding the ribbon longitudinally a suitable distance, the springs .2 returning them to their first positions as the bar E again moves forward.

Each ratchet-wheel 11' is prevented by a click-spring or detent Z) from being turned backward by the pawl or dog aon its backward movement. This detent must be thrown out of engagement with its ratchet wheel whenever the pawl is, so as to permit backward rotation and allow the ribbon to be drawn off and wound upon the spool being actuated, or else the ribbon-spools must be transposed when the direction of travel is to be reversed. It is preferred to disengage the detent from the ratchet-wheel, as handling of the ribbon is thereby obviated.

The present application is a division of application Serial No. 34.0,920, filed in the name of Christopher Latham Sholes, on the 18th day of February, 1890, upon which Letters Patent numbered 559,755 were issued May 5, 1896, and any matters herein illustrated or referred to, but not distinctly claimed, have been reserved to the parent application.
